Description

Die Erfindung betrifft ein Befestigungselement zum Einsetzen in eine rechteckige, insbesondere quadratische Öffnung in einer Wand, insbesondere an einer Fahrzeugkarosserie, mit einem Hals zum Durchgreifen der Öffnung, wobei die Querschnittskontur des Halses die Form eines Rechtecks, insbesondere eines Quadrats hat, einem an dem Hals angeordneten Flansch, der den die Öffnung umgebenden Randbereich der Wand überdeckt, wenn das Befestigungselement in der Öffnung angeordnet ist, einer durch den Flansch in den Hals ragenden Bohrung zur Aufnahme einer Schraube und mit wenigstens zwei federnden Rastnasen zum Festhalten des Befestigungselements in der Öffnung der Wand.The invention relates to a fastener for insertion in a rectangular, in particular square opening in a wall, in particular on a vehicle body, with a neck for reaching through the opening, wherein the Cross-sectional contour of the neck the shape of a rectangle, in particular a square, one arranged at the neck Flange, which surrounds the edge area surrounding the opening the wall is covered when the fastener in the opening is arranged, one through the flange in the Necked bore for receiving a screw and with at least two resilient detents for holding the Fastener in the opening of the wall.

Derartige Befestigungselemente sind mit dem Hals in der Öffnung der Wand gegen Verdrehen gesichert und können daher bei dem Eindrehen einer Befestigungsschraube in die Bohrung ein dem Eindrehmoment entgegenwirkendes Gegendrehmoment auf die Wand übertragen. Mit Hilfe der Rastnasen sind sie gegen Herausziehen aus der Öffnung gesichert. Um eine möglichst hohe axiale Haltekraft zu erreichen, sind bekannte Befestigungselemente der angegebenen Art an allen vier Seiten mit federnden Rastnasen versehen. Hierbei hat sich gezeigt, daß nur ein begrenzendes Gegendrehmoment für das Eindrehen von Schrauben erreicht werden kann. Treffen ungünstige Maßabweichungen von Schraube oder Bohrung aufeinander, so kann es zum Durchdrehen des Befestigungselementes und dadurch zur Beeinträchtigung des Montagevorganges kommen.Such fasteners are with the neck in the Opening the wall secured against twisting and can Therefore, when screwing a fixing screw in the Bore a torque counteracting the insertion torque transferred to the wall. With the help of the locking lugs they are secured against being pulled out of the opening. Around to achieve the highest possible axial holding force, are known fasteners of the specified type at all four sides provided with resilient locking lugs. This has shown that only a limiting counter torque for the screwing in of screws can be achieved. To meet unfavorable dimensional deviations of screw or bore, so it can cause the fastener to spin and thereby affecting the assembly process come.

Der Erfindung liegt die Aufgabe zugrunde, ein Befestigungselement der eingangs angegebenen Art zu schaffen, welches bei ausreichender axialer Haltekraft ein möglichst hohes Drehmoment auf eine Wand übertragen kann.The invention is based on the object, a fastener to provide the type specified, which with sufficient axial holding force as possible can transmit high torque to a wall.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß ausschließlich an zwei gegenüberliegenden Seiten des Halses Rastnasen vorgesehen und jeweils in einen elastisch verformbaren Wandabschnitt des Halses integriert sind und daß die elastisch verformbaren Wandabschnitte durch zwei steife Wandabschnitte verbunden sind, die keine Rastnasen tragen.According to the invention the object is achieved in that exclusively on two opposite sides of the neck Latch provided and each in an elastically deformable Wall section of the neck are integrated and that the elastically deformable wall sections by two rigid wall sections are connected, which are no latching noses wear.

Es wurde gefunden, daß durch die erfindungsgemäße Gestaltung des Befestigungselements eine ausreichende Elastizität im Bereich der Rastnasen, eine ausreichende Haltekraft und ein torsionssteifer Hals geschaffen werden kann, der geeignet ist, vergleichsweise große Drehmomente auf die Wand zu übertragen. Das Befestigungselement eignet sich daher besonders für selbstschneidende und selbstsichernde Schrauben, die ein verhältnismäßig hohes Eindrehmoment benötigen.It has been found that by the inventive design of the fastener sufficient elasticity in the area of the locking lugs, a sufficient holding force and a torsionally rigid neck can be created which is suitable, comparatively large torques on the Wall to transfer. The fastener is suitable therefore especially for self-tapping and self-locking Screws that have a relatively high insertion torque need.

Die Wände, welche die Rastnasen tragen, können nach einem weiteren Vorschlag der Erfindung durch sich in Längsrichtung erstreckende Aussparungen in einen äußeren, federnden Wandabschnitt und einen inneren, federnden Wandabschnitt unterteilt sein.The walls, which carry the detents, can after a further proposal of the invention by itself in the longitudinal direction extending recesses in an outer, resilient Wall section and an inner, resilient wall section be divided.

Nach einem weiteren Vorschlag der Erfindung kann vorgesehen sein, daß der Flansch des Befestigungselementes quer zu seiner Erstreckung elastisch verformbar ist und daß die Haltemittel zum Festhalten des Befestigungselementes in der Öffnung der Wand so ausgebildet sind, daß die Einbaulage des Befestigungselementes nur durch elastische Verformung des mit seinem Umfangsrand an der Wand abgestützten Flansches erreichbar ist. Auf diese Weise bildet der Flansch ein federndes Element, welches bei der Montage des Befestigungselements gespannt wird und das Befestigungselement in axialer Richtung spielfrei hält. Zusätzlich wird mit einfachen Mitteln ein ausreichender Federweg zum Ausgleich von fertigungsbedingten Maßabweichungen erreicht.According to another proposal of the invention can be provided be that the flange of the fastener transversely to its extension is elastically deformable and that the Holding means for holding the fastener in the opening of the wall are formed so that the mounting position the fastener only by elastic deformation of the supported with its peripheral edge on the wall Flange is reachable. In this way, the forms Flange a resilient element, which during assembly of the Fastener is clamped and the fastener keeps free of play in the axial direction. additionally is with simple means sufficient spring travel to Compensation of production-related deviations reached.

Die Rastnasen haben vorzugsweise jeweils eine Einführschräge und eine Abstützfläche haben, wobei die Einführschrägen zum Zusammendrücken der Rastnasen beim Einsetzen in eine Wandöffnung dienen und die Abstützflächen geeignet sind, nach dem Entspannen der Rastnasen sich auf der dem Flansch abgekehrten Seite an der Wand abzustützen.The locking lugs preferably each have an insertion bevel and have a support surface, wherein the insertion bevels for compressing the locking lugs when inserting serve in a wall opening and the support surfaces suitable are, after relaxing the locking lugs on the Flange facing away from the wall.

Nach einem weiteren Vorschlag der Erfindung kann das Befestigungselement einen den Hals auf der dem Flansch abgekehrten Seite verlängernden Schaft aufweisen, in den sich die Bohrung zur Aufnahme einer Schraube hinein erstreckt. Das freie Ende des Schaftes kann geschlossen sein, um einen dichten Verschluß der Öffnung zu ermöglichen.According to a further proposal of the invention, the fastening element a neck on the flange turned away Side extending shaft into which the bore extends to receive a screw. The free end of the shaft can be closed to to allow a tight closure of the opening.

Bei dem in den Figuren 1 bis 3 dargestellten Befestigungselement 1 handelt es sich um einen Dübel aus Kunststoff, der zum Einsetzen in eine quadratische Öffnung in einer Wand aus Blech, z.B. an einer Fahrzeugkarosserie bestimmt ist, um mittels einer in den Dübel eingedrehten Schraube ein Anbauteil an der Wand befestigen zu können.In the fastener shown in Figures 1 to 3 1 is a plastic dowel, for insertion into a square opening in one Wall of sheet metal, e.g. determined on a vehicle body is to, by means of a screw screwed into the dowel attach a fixture to the wall.

Das Befestigungselement 1 besteht aus einer langgestreckten Hülse 2 mit einer zentralen Bohrung 3, die an einem Ende verschlossen ist. An das offene Ende der Hülse 2 ist ein kreisrunder, koaxial zur Bohrung 3 angeordneter Flansch 4 angeformt, der an allen Seiten von der Hülse 2 absteht. Der Flansch 4 weist auf seiner der Hülse 2 zugekehrten Unterseite eine ringförmige Vertiefung 5 auf. Radial nach innen wird die Vertiefung 5 von der Außenfläche der Hülse 2 und radial nach außen von einem Umfangsrand 6 des Flansches 4 begrenzt.The fastening element 1 consists of an elongated Sleeve 2 with a central bore 3, which at a End is closed. At the open end of the sleeve 2 is a circular, coaxial with the bore 3 arranged Flange 4 formed on all sides of the sleeve. 2 projects. The flange 4 has on its the sleeve 2 facing Bottom of an annular recess 5 on. Radially inward, the recess 5 from the outer surface the sleeve 2 and radially outward from a peripheral edge 6 of the flange 4 limited.

Die Außenfläche der Hülse 2 hat im wesentlichen die Form einer Stufenpyramide mit quadratischer Grundfläche, wobei die Pyramidenspitze das geschlossene Hülsenende bildet. Der sich an den Flansch 4 anschließende Pyramidenfuß bildet einen Hals 7, der in der Einbaulage des Befestigungselementes 1 in die Wandöffnung eingreift. Durch seine vierkantige Form ist der Hals 7 in einer entsprechend gestalteten Öffnung gegen Verdrehen gesichert und in der Lage, ein dem Eindrehmoment einer in die Bohrung 3 eingedrehten Schraube entgegenwirkendes Gegendrehmoment auf die Wand zu übertragen.The outer surface of the sleeve 2 has substantially the shape a stepped pyramid with a square base, where the pyramid tip forms the closed sleeve end. The adjoining the flange 4 Pyramidenfuß forms a neck 7, which in the installation position of the fastener 1 engages in the wall opening. By his Four-edged shape is the neck 7 in a corresponding formed opening against twisting and secured in the Lage, a screwing the torque of a screwed into the bore 3 Screw counteracting counter torque on the Wall to transfer.

Auf zwei entgegengesetzten Seiten weist der Hals 7 nach außen vorspringende Rastnasen 8 auf, die dem geschlossenen Hülsenende zugekehrte Einführschrägen 9 und dem Flansch 4 gegenüberliegende Abstützflächen 10 haben. Im Bereich der Rastnasen 8 ist die Hülsenwand durch sich parallel zur Bohrung 3 erstreckende Aussparungen 11 geschwächt. Hierdurch wird die elastische Verformbarkeit der die Rastnasen 8 tragenden Wandabschnitte 12 so weit erhöht, daß die Rastnasen 8 beim Einsetzen des Befestigungselementes 1 in eine Öffnung durch den Kontakt ihrer Einführschrägen 9 mit dem Öffnungsrand nach innen gedrückt werden können, um so die im Vergleich zum Abstand der Rastnasen 8 engere Wandöffnung zu passieren. Die Abstützflächen 10 der Rastnasen 8 sind zur Anlage an der dem Flansch 4 entgegengesetzten Seite der das Befestigungselement 1 aufnehmenden Wand bestimmt. Ihr Abstand von der Berührungsebene des Umfangsrandes 6 ist etwas kleiner als die Dicke der Wand, für die das Befestigungselement bestimmt ist. Wird das Befestigungselement 1 in die Öffnung der Wand eingesetzt, so muß daher durch axialen Druck auf die Hülse 2 der mit seinem Umfangsrand 6 an der Wand anliegende Flansch 4 elastisch verformt werden, damit die Rastnasen 8 auf der anderen Seite aus der Wandöffnung heraustreten und sich dort mit ihren Abstützflächen 10 an die Wand anlegen können.On two opposite sides of the neck 7 outside projecting locking lugs 8, which the closed Sleeve end facing chamfers 9 and the flange 4th opposite support surfaces 10 have. Around Latches 8 is the sleeve wall through parallel to Bore 3 extending recesses 11 weakened. hereby the elastic deformability of the locking lugs 8 supporting wall sections 12 so far increased that the Latches 8 when inserting the fastener 1 in an opening through the contact of their chamfers 9 with the opening edge can be pressed inwards so the narrower compared to the distance of the locking lugs 8 wall opening to happen. The support surfaces 10 of the locking lugs 8 are opposed to the flange 4 to the plant Side of the fastening element 1 receiving wall certainly. Your distance from the plane of contact of the peripheral edge 6 is slightly smaller than the thickness of the wall, for the the fastener is determined. Will the fastener 1 inserted into the opening of the wall, so must Therefore, by axial pressure on the sleeve 2 with his Peripheral edge 6 on the wall fitting flange 4 elastic be deformed so that the locking lugs 8 on the other Side emerge from the wall opening and there with their support surfaces 10 can invest on the wall.

Die Wandabschnitte 13 des Halses 7, die keine Rastnasen 8 tragen, sind steif ausgebildet. Sie ermöglichen dadurch die Aufnahme hoher Haltekräfte an einer in die Bohrung 3 eingedrehten Schraube und die Übertragung eines hohen Drehmoments auf die das Befestigungselement 1 aufnehmende Wand.The wall portions 13 of the neck 7, which are no latching noses 8 wear, are stiff. They make it possible the inclusion of high holding forces on a in the bore. 3 screwed in and the transmission of a high Torque on the fastening element 1 receiving Wall.

Der sich an den Hals 7 anschließende Abschnitt der Hülse 2 bildet einen Schaft 14, dessen Pyramidenspitze das Einführen des Befestigungselementes 2 in eine Öffnung erleichtert.The adjoining the neck 7 section of the sleeve. 2 forms a shaft 14, the pyramid tip insertion the fastener 2 is facilitated in an opening.

Die Aussparungen 11 sind an ihren seitlichen Enden durch radiale Schlitze 15 mit der Bohrung 3 verbunden. Hierdurch sind radial federnde Zungen 16 gebildet, die durch Eindrehen einer Schraube in die Bohrung 3 radial nach außen gedrückt werden und sich an die Wandabschnitte 12 anlegen. The recesses 11 are at their lateral ends by radial slots 15 connected to the bore 3. hereby are radially resilient tongues 16 formed by screwing a screw in the bore 3 radially outward be pressed and create the wall sections 12.

Das Schraubengewinde schneidet nur in die Wandabschnitte 13 und die Wand des Schafts 14 ein. Die Zungen 16 füllen den Zwischenraum zwischen der Schraube und den Wandabschnitten 12 aus und stützen dadurch die Wandabschnitte 12 radial nach innen ab. Hierdurch werden die Rastnasen 8 in ihrer Halteposition verriegelt, so daß das in einer Wandöffnung montierte Befestigungselement 1 zusätzlich gegen Lösen gesichert ist.The screw thread cuts only in the wall sections 13 and the wall of the shaft 14 a. Fill the tongues 16 the space between the screw and the wall sections 12 and thereby support the wall sections 12th radially inward. As a result, the locking lugs 8 in locked their holding position, so that in a wall opening mounted fastener 1 additionally against Loosening is secured.

Zum Abdichten einer das Befestigungselement 1 aufnehmenden Öffnung in einer Wand kann in der Vertiefung 5 des Flansches 4 ein Dichtring angeordnet werden, der bei der Montage des Befestigungselementes 1 zwischen dem Flansch 4 und der Wand eingespannt wird.For sealing a fastening element 1 receiving Opening in a wall can be in the recess 5 of the flange 4 a sealing ring can be arranged during assembly of the fastening element 1 between the flange 4th and the wall is clamped.

In Figur 4 ist die Einbaulage des Befestigungselementes 1 veranschaulicht. Das Befestigungselement 1 befindet sich hierbei in einer quadratischen Öffnung 18 in einer Wand 19. In dieser Lage wird es durch die Rastnasen 8 festgehalten, die mit ihren Abstützflächen 10 an der in Einsteckrichtung gesehen hinteren Wandfläche 20 anliegen. Der Flansch 4 wurde bei der Montage des Befestigungselementes 1 durch Druck auf die Hülse 2 entgegen der Einsteckrichtung elastisch verformt und stützt sich daher mit seinem Umfangsrand 6 mit einer der Verformungskraft entsprechenden Kraft an der vorderen Wandfläche 21 ab.FIG. 4 shows the installation position of the fastening element 1 illustrated. The fastener 1 is located this in a square opening 18 in a wall 19. In this position, it is held by the locking lugs 8, the with their support surfaces 10 at the insertion seen rear wall surface 20 abut. Of the Flange 4 was used during assembly of the fastener 1 by pressure on the sleeve 2 against the insertion elastically deformed and therefore supports with his Peripheral edge 6 with a deformation force corresponding Force on the front wall surface 21 from.
